Evidence for a General Neural Signature of Face Familiarity.

TLDR
This paper explored the neural signatures of face familiarity using cross-participant and cross-experiment decoding of event-related potentials, evoked by unknown and experimentally familiarized faces from a set of experiments with different participants, stimuli, and familiarization-types.
Abstract
We explored the neural signatures of face familiarity using cross-participant and cross-experiment decoding of event-related potentials, evoked by unknown and experimentally familiarized faces from a set of experiments with different participants, stimuli, and familiarization-types. Human participants of both sexes were either familiarized perceptually, via media exposure, or by personal interaction. We observed significant cross-experiment familiarity decoding involving all three experiments, predominantly over posterior and central regions of the right hemisphere in the 270-630 ms time window. This shared face familiarity effect was most prominent across the Media and the Personal, as well as between the Perceptual and Personal experiments. Cross-experiment decodability makes this signal a strong candidate for a general neural indicator of face familiarity, independent of familiarization methods, participants, and stimuli. Furthermore, the sustained pattern of temporal generalization suggests that it reflects a single automatic processing cascade that is maintained over time.

A neural measure of the degree of face familiarity

TL;DR: In this paper , the authors measured face familiarity using subjective familiarity ratings in addition to testing explicit knowledge and reaction times in a face matching task, and found that the neural representations of familiar faces form part of a general neural signature of the familiarity component of recognition memory processes.

No semantic information is necessary to evoke general neural signatures of face familiarity: evidence from cross-experiment classification

TL;DR: In this article , a cross-experiment multivariate pattern classification analysis (MVPA) was applied to test if EEG patterns for passive viewing of personally familiar and unfamiliar faces are useful in decoding familiarity in a matching task where familiarity was attained thorough a short perceptual task.

The neural dynamics of familiarity-dependent face identity representation.

TL;DR: In this article , the authors performed a multivariate EEG analysis to examine the representational dynamics of face identity across several familiarity levels and found that the degree of familiarity modulates the available identity-specific information at relatively early time window.

The Fusiform Face Area: A Module in Human Extrastriate Cortex Specialized for Face Perception

TL;DR: The data allow us to reject alternative accounts of the function of the fusiform face area (area “FF”) that appeal to visual attention, subordinate-level classification, or general processing of any animate or human forms, demonstrating that this region is selectively involved in the perception of faces.

Neural systems for recognition of familiar faces.

TL;DR: It is hypothesized that the "theory of mind" areas, that have been implicated in social and cognitive functions other than face perception, play an essential role in the spontaneous activation of person knowledge associated with the recognition of familiar individuals.
